Measuring factors affecting grip strength in a Taiwan Chinese population and a comparison with consolidated norms.
We inquire whether assessment of an individual's upper limb function may be improved by using specific regional norms rather than consolidated global norms. Grip strengths were measured in a sample of 482 adults across Taiwan, and compared with consolidated norms. To ensure comparable conditions, our procedures were those recommended by the American Society of Hand Therapists (ASHT). Overall the mean grip strength of our sample was significantly (male 25%, female 27%) lower than consolidated norms derived from largely Caucasian populations. We investigated variables that might relate to this divergence. Results of ANOVA and stepwise multiple regression analysis showed that gender, age and palm length were effective predictors in grip strength. A regression equation was derived. When other variables were matched, palm length appeared an important discriminating factor. Further anthropometric and socio-economic factors also need investigation. Specific regional norms should provide more accuracy for ergonomists and health workers assessing an individual's upper limb function, and may avoid errors in appraisal. This paper suggests grip strength values for Taiwan.
